Comparisons of blink-startle response (orbicularis oculi EMG) to loud tones across sessions and between times-of-day. A. First Session-Pair Analyses of EMG Mean Response percentage change from session 1 to session 2 showing a significant difference between PAPA (PM to AM) and APAPA (AM to PM) groups (N=11 APAPA, 15 PAPA). B. First Session-Pair Analyses of EMG Relative Habituation showing significantly greater intra-session habituation (more negative correlation coefficient) in the second (AM) compared to first (PM) session of the APAPA group (N=11 APAPA, 15 PAPA). C. Analyses by Session-Order for Change Across Session Pairs across 2 PM to AM sessions in the PAPA group compared to 2 AM to PM changes in the APAPA group (p < .05 for Group x Session Pair interaction) (N=7 APAPA, 11 PAPA). D. Time-of-day analysis collapsing across groups showing lack of a Time-of-Day (AM vs. PM) main effect (N=18). EMG μV1/2 (or EMG1/2) square-root transformed electromyographic response in microVolts, * p < .05, ** p < .01, Error bars depict standard error of the mean.
